WZ' INEE 5f 5 UNITED STATES PATENT OFFICEo WILLIAM D. MASON, OF PROVIDENCE, RHODE ISLAND,

DROP-LlGHT ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 384,052, dated June 5, 1888.

Application filed July i9, 1887.

To aZZ whom, t may concern.-

Be it known that I, WILLIAM D. MAsoN, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Drop-Light Attachments, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming part of this specication.

This invention relates to what is known as a storlcuecli attachment for droplights, and which is a device for temporarily connecting the iexible-tube of the drop-light with a gasburner in order to supply the drop with gas. In these storlcneck attachments the pipe forming the curved-neck part is required to make a very short bend or curve relative to the gas- 'socket connected therewith, in order that the attachment may be convenientlyT entered through the base-opening of an ordinary globe aud readily secured to or removed from the burner through such opening.

The objects of my invention are to provide a neat and compact attachment or storlcneck, which may be made very cheaply and strongly, and which will be a very efficient article for the purpose of its design.

To the aforesaid purposes my invention consists, essentially, in connecting the gas socket piece with the curved gas-tube by means ofan elbow-pipe coupling, as hereinafter fully de. scribed and claimed.

In the accompanying drawings, illustrating my invent-ion, Figure lis a side view of a portion of a gas-bracket provided with a gasburner to which my improved Stork-neck attachment is connected. The' gas-bracket is also shown as having a globe-holder mounted thereon, with a globe set thereon and indicated in broken lines. Fig. 2- is anenlarged longitudinal sectional detail view of the improved attachment, and shows the. curved gas-tube yand the elbow-coupling piece secured to the upper curved end of the tube, and the gas-socket also secured to the coupling-piece.

.In Athe said drawings like numbers of reference designate corresponding parts throughout.

Serial Nam-1,703. (No model.)

Referring to the drawings, the number 4 designates a portion of an ordinary gasbracket provided with the gasburner 5, and having the globeholder Gsecured thereupon and supporting the globe 7, which is indicated in broken lines.

My improvement consists in connecting the bent gas-tube 8 with the straight gas-socket piece 9, which fits over the gas-burner by means of the elbow-coupling 10,which is formed with a channel or bore, 11, running at right angles or L-shaped through it, one mouth of which channel is internally-screw-threaded, as at 12, and the other of which is externally-screwthreaded, as at 13. The gassocket 9 is iuternally-screw-threaded and screwed upon the end 13 of the coupling,while the bent gas tube is secured to the coupling by means of the externally-screwthreaded end thereof being inserted within the mouth 12 of the coupling.

However, the gas-tube 8 may be secured to the coupling merely by soldering the end within the mouth of the coupling without the use of the screwthreads.

To the lower end ot' the gas-tube is attached the iieXible drop-pipe 14, which is shown in` position in Fig. 1, and which is designed to connect with a gas-stand. (Not shown.)

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1 In a 'detachable storlcneck attachment, the combination, with the internallyscrew-threaded gas-socket 9 for receiving the gas-burner, and the externally-screw-threaded bent gastube 8, of the elbow-coupling l0, connecting the socket and the tube and provided with the right-angled channel or bore 11, and formed with the internal screw-thread, 12, and the external screwthread, 13, substantially as and for the purpose herein described.

In witness whereof I have hereunto set my hand.

WILLIAM i). MASON.
